PORegex Group in Perl: how to capture elements into array from regex group that matches unknown number of/multiple/variable occurrences from a string?
text
Body
copied!<p>In Perl, how can I use one regex grouping to capture more than one occurrence that matches it, into several array elements?</p> <p>For example, for a string:</p> <pre><code>var1=100 var2=90 var5=hello var3="a, b, c" var7=test var3=hello </code></pre> <p>to process this with code:</p> <pre><code>$string = "var1=100 var2=90 var5=hello var3=\"a, b, c\" var7=test var3=hello"; my @array = $string =~ <regular expression here> for ( my $i = 0; $i < scalar( @array ); $i++ ) { print $i.": ".$array[$i]."\n"; } </code></pre> <p>I would like to see as output:</p> <pre class="lang-none prettyprint-override"><code>0: var1=100 1: var2=90 2: var5=hello 3: var3="a, b, c" 4: var7=test 5: var3=hello </code></pre> <p>What would I use as a regex?</p> <p>The commonality between things I want to match here is an assignment string pattern, so something like:</p> <pre><code>my @array = $string =~ m/(\w+=[\w\"\,\s]+)*/; </code></pre> <p>Where the * indicates one or more occurrences matching the group.</p> <p>(I discounted using a split() as some matches contain spaces within themselves (i.e. var3...) and would therefore not give desired results.)</p> <p>With the above regex, I only get:</p> <pre><code>0: var1=100 var2 </code></pre> <p>Is it possible in a regex? Or addition code required?</p> <p>Looked at existing answers already, when searching for "perl regex multiple group" but not enough clues:</p> <ul> <li><a href="https://stackoverflow.com/questions/3159991/dealing-with-multiple-capture-groups-in-multiple-records">Dealing with multiple capture groups in multiple records</a></li> <li><a href="https://stackoverflow.com/questions/1313332/multiple-matches-within-a-regex-group">Multiple matches within a regex group?</a></li> <li><a href="https://stackoverflow.com/questions/3172643/regex-repeated-capturing-groups">Regex: Repeated capturing groups</a> </li> <li><a href="https://stackoverflow.com/questions/446126/regex-match-and-grouping">Regex match and grouping</a></li> <li><a href="https://stackoverflow.com/questions/1407435/how-do-i-regex-match-with-grouping-with-unknown-number-of-groups">How do I regex match with grouping with unknown number of groups</a></li> <li><a href="https://stackoverflow.com/questions/1116193/awk-extract-multiple-groups-from-each-line">awk extract multiple groups from each line</a></li> <li><a href="https://stackoverflow.com/questions/1791097/matching-multiple-regex-groups-and-removing-them">Matching multiple regex groups and removing them</a></li> <li><a href="https://stackoverflow.com/questions/2685456/perl-deleting-multiple-re-occuring-lines-where-a-certain-criteria-is-met">Perl: Deleting multiple reccuring lines where a certain criterion is met</a></li> <li><a href="https://stackoverflow.com/questions/2398730/regex-matching-into-multiple-groups-per-line">Regex matching into multiple groups per line?</a></li> <li><a href="https://stackoverflow.com/questions/1087720/php-regex-grouping-multiple-matches">PHP RegEx Grouping Multiple Matches</a></li> <li><a href="https://stackoverflow.com/questions/3246237/how-to-find-multiple-occurances-with-regex-groups">How to find multiple occurrences with regex groups?</a></li> </ul>
